摘要：

The ability to suppress the recombination of the photoinduced charges is the key prerequisite for an excellent photocatalyst, which has attracted extensive and continuous interest in the field of photocatalysis. Herein, we presented a convenient strategy for the one-step selective synthesis of ultrathin BiOBr nanosheets with atomic thickness through a simple solvothermal method. These ultrathin BiOBr nanosheets not only show high exposure percentage of active (001) facets but also have an optimized band structure, which synergistically facilitates the electron-hole pair separation to realize significantly promoted visible-light photocatalytic activity. Our results provide a new avenue and direction for the design of photocatalysts with high visible-light photocatalytic performance.
